Dowel Drilling Guide Quick-Action Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for drilling dowel holes in panel bodies require complex and time-consuming manual adjustments and fixing processes, which can lead to inaccuracies and increased production time.
Innovation Solution
A quick-action clamping device with an adjustable clamping force is integrated into the drilling template, allowing for secure and simplified fixing and adjustment of the drilling template relative to the base body, using a spring-loaded clamping mandrel and pivotable clamping lever to facilitate easy alignment and secure positioning of guide holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manually operable locking screws are used to fix the drilling template to the base body, then secure fixing is achieved, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The patent implements a dynamic quick-action clamping device where the clamping lever can be easily pivoted between locked and unlocked positions. The clamping mandrel is spring-loaded to automatically engage with the drilling template when the lever is in the locked position, and disengage when the lever is pivoted to the unlocked position. This dynamic mechanism replaces static manual screw tightening with a simple lever movement, dramatically reducing adjustment time while maintaining secure fixing.
Solution Approach 2:
The patent extracts the time-consuming manual screw tightening operation from the fixing process. Instead of requiring operators to manually tighten multiple locking screws, the invention uses a lever-operated mechanism where a single pivoting motion simultaneously controls the engagement of spring-loaded clamping mandrels, removing the tedious manual adjustment step while preserving reliable fixation.
2Reliability
If manual screw adjustments are required for fixing the drilling template, then secure positioning is achieved, but the process becomes complex and requires multiple steps
Solution Approach 1:
The patent merges multiple independent screw tightening operations into a single integrated lever mechanism. The clamping lever is connected to spring-loaded clamping mandrels that simultaneously engage with the drilling template when the lever is actuated. This combines what would otherwise be multiple separate fixing operations into one unified action, simplifying the process while maintaining secure positioning through the combined force of multiple clamping elements.
Solution Approach 2:
The spring-loaded clamping mandrels provide self-service by automatically engaging and applying clamping force when the lever is positioned in the locked state, without requiring manual tightening. The springs automatically maintain the clamping force, and the system self-regulates to provide secure positioning without complex manual adjustment procedures.
3Reliability
If multiple locking screws are used to secure the drilling template, then reliable fixing is achieved, but the adjustment and repositioning process becomes time-consuming
Solution Approach 1:
The patent transforms the static, multi-step screw tightening process into a dynamic, single-motion lever operation. The clamping lever is designed to pivot quickly between locked and unlocked positions, and the spring-loaded mandrels respond dynamically to the lever's position, automatically engaging or disengaging to maintain reliable fixing while enabling rapid adjustment and repositioning of the drilling template.
